NFSv4: Fix a state manager thread deadlock regression

Browse source

Commit 4dc73c6791 reintroduces the deadlock that was fixed by commit
aeabb3c961 ("NFSv4: Fix a NFSv4 state manager deadlock") because it
prevents the setup of new threads to handle reboot recovery, while the
older recovery thread is stuck returning delegations.

Fixes: 4dc73c6791 ("NFSv4: keep state manager thread active if swap is enabled")
